Description

Technical Field

[0001] The invention relates to the technical field of workpiece drilling processing, in particular to an automatic numerical control processing device. Background Art

[0002] Automated CNC machining equipment is a device used for high-precision and high-efficiency processing of metal and non-metal materials. Through computer program control, CNC machining equipment can perform various types of processing operations, such as drilling, cutting, milling, turning and grinding. This device is usually suitable for batch production and high-precision workpiece processing, and is widely used in aerospace, automobile manufacturing, mold processing, precision instruments and other industries. Among them, drilling is one of the most common processing methods for CNC machining equipment, especially suitable for the processing of cylindrical workpieces. Axial drilling and radial drilling on cylindrical workpieces is one of the requirements of CNC machining. This combined drilling structure is usually used for parts such as hydraulic valve bodies, injectors, cooling pipes, drive shafts, etc. The purpose is to achieve functions such as fluid guidance, cooling, lubrication or installation of auxiliary holes in internal channels.

[0003] The following problems exist in the process of combined drilling of cylindrical workpieces by traditional methods: when processing radial holes, the drill rod usually needs to be adjusted inclination according to a predetermined angle, and after the inclination is adjusted, it is also necessary to limit the position according to the drilling position to prevent deviation during drilling. Multiple operation steps are scattered, especially when processing multiple consecutive radial holes on a cylindrical workpiece, each drilling requires separate inclination adjustment and limit control operations, resulting in cumbersome processing steps and a long cycle; and in the process of axial drilling, as the depth of the hole gradually increases, it is difficult for the coolant to effectively reach the working position of the drill bit, which will cause the drill bit to overheat, aggravate tool wear, and affect the drilling accuracy and quality.

[0004] In addition, during the combined drilling process of cylindrical workpieces, usually only one end of the cylindrical workpiece is clamped, causing the other end of the cylindrical workpiece to be suspended in the air to form a cantilever beam structure. Due to the lack of support at the suspended end, displacement or vibration is likely to occur during the processing, causing the axial and radial drilling positioning to shift, affecting the processing accuracy, which is particularly obvious during radial drilling or deep hole processing. Summary of the invention

[0005] The present invention provides an automated CNC machining device, which solves the problem that when performing combined drilling on a cylindrical workpiece, radial hole machining requires repeated inclination adjustment and limit control, and the operation steps are cumbersome and time-consuming, especially in continuous drilling. In axial drilling, as the hole depth increases, it is difficult for the coolant to effectively reach the drill bit, resulting in overheating and wear, affecting the accuracy. In addition, clamping only one end of the workpiece during the drilling process will cause the other end to be suspended, forming a cantilever structure without support, resulting in displacement and vibration during the machining process, which reduces the hole position accuracy. The technical problems are particularly prominent in radial and deep hole machining.

[0033] See also Figure 2 , Figure 3 and Figure 4The pushing assembly 59 includes a rectangular frame 591 slidably connected to the outside of the C-shaped frame 3, an electric telescopic rod 592 is fixedly connected between the rectangular frame 591 and the C-shaped frame 3, two pairs of push rods 593 corresponding to the rotating shaft 52 are hinged symmetrically on the left end surface of the rectangular frame 591, a lever 594 is fixedly connected to the outside of the ring sleeve 58, a push column is hinged at one end of the lever 594 away from the ring sleeve 58, and a strip frame 595 is fixedly connected to one end of the push column away from the lever 594, and a push block 596 slidably connected to the strip frame 595 is fixedly connected to the opposite sides of the front and rear push rods 593, and a top spring is fixedly connected between the push block 596 and the strip frame 595, and arc-shaped limit grooves 9 are provided on the front and rear sides of the positioning clamp seat 51, and a limit column 10 slidably set in the arc-shaped limit groove 9 is fixedly connected to the side of the lever 594 close to the positioning clamp seat 51.

[0034] See also Figure 5 and Figure 6 The sliding assembly 54 includes two guide grooves 541 symmetrically arranged on the inner wall of the mounting tube 53 along the axis and a mounting plate 542 slidably connected between the two guide grooves 541, a return spring is fixedly connected between the mounting plate 542 and the guide groove 541, the drilling rig 55 is fixedly connected to the left end surface of the mounting plate 542, a push rod 543 is fixedly connected to the right side of the mounting plate 542, and an inclined pressure plate 6 cooperating with the push rod 543 is fixedly connected between the two corresponding front and rear push rods 593 through a connecting frame.

[0035] Since the self-clamping positioning radial drilling mechanism 5 is located on the left side of the synchronous cooling axial drilling mechanism 4, the radial drilling operation from right to left for the cylindrical workpiece will be performed before the axial drilling operation. The initial position of the mounting cylinder 53 is horizontal. At this time, the distance between the two positioning clamps 51 is greater than the diameter of the cylindrical workpiece to be processed. First, the left end of the cylindrical workpiece is placed in the clamping part 2 for clamping and limiting, and then the electric slide 11 is controlled to drive the C-shaped frame 3 to move to the left. The C-shaped frame 3 then drives the self-clamping positioning radial drilling mechanism 5 to move to the outside of the cylindrical workpiece, and then the electric slide 11 is controlled to stop.

[0036] Then the electric telescopic rod 592 is controlled to extend to push the rectangular frame 591 to move leftward, and the rectangular frame 591 then pushes the push rod 593 to move leftward, and the push rod 593 then pushes the push column to move leftward through the push block 596, the top spring and the strip frame 595, and the push column then pushes the lever 594 to drive the ring sleeve 58 to rotate, and the ring sleeve 58 then drives the rotating shaft 52 to rotate through the torsion spring 510, and the rotating shaft 52 then drives the installation cylinder 53 and the convex dial wheel 56 to rotate synchronously. When the convex dial wheel 56 starts to rotate, its protrusion will touch the inner wall of the sun-shaped frame 57. Then, the upper and lower positioning clamps 51 are pushed and moved closer to each other, and the mounting tube 53 rotates and gradually tilts. When the convex dial wheel 56 rotates and contacts the sun-shaped frame 57, driving the two positioning clamps 51 to be tightly clamped on the outside of the cylindrical workpiece, the rotating shaft 52 stops rotating, and the lever 594 is continued to be pushed and drives the ring sleeve 58 to continue to rotate. The ring sleeve 58 then causes the torsion spring 510 to be gradually compressed until the lever 594 drives the limit column 10 to slide and contact the left end of the arc-shaped limit groove 9. At this time, the mounting tube 53 also rotates to the required tilted position.

[0037] At this time, the electric telescopic rod 592 continues to extend to push the rectangular frame 591 to move left, and the rectangular frame 591 then drives the push rod 593 to move left. The push rod 593 then drives the push block 596 to slide in the bar frame 595 and drives the top spring to be compressed. The push rod 593 that continues to move left drives the inclined pressure plate 6 to move through the connecting frame. After the inclined pressure plate 6 moves to the left, its inclined surface will contact the push rod 543, and then squeeze the upper end of the push rod 543. The push rod 543 is then pushed downward, and the push rod 543 drives the mounting plate 542 to move downward. The mounting plate 542 then drives the drilling rig 55 to move downward. The drilling rig 55 then moves downward and contacts the outside of the cylindrical workpiece, so that radial inclined drilling can be performed on the cylindrical workpiece.

[0038] After the radial drilling is completed, the electric telescopic rod 592 is controlled to shrink and pull the rectangular frame 591 to move right, and the rectangular frame 591 then drives the push rod 593 to move right, and the push rod 593 then drives the inclined pressure plate 6 to move right. At the same time, the push rod 593 also drives the push block 596 to move right in the strip frame 595, and the inclined pressure plate 6 moves to the right until it is separated from the push rod 543, and the reset spring pushes the mounting plate 542 to move up, and the mounting plate 542 then drives the push rod 543 and the drilling rig 55 to move up to the initial position, and the push block 596 also moves to the right until it contacts the right cavity wall of the strip frame 595, and then the push block 596 pulls the strip frame 595 to move right, and the strip frame 595 then rotates by pulling the lever 594 through the push column, and the lever 594 drives the ring sleeve 58 to rotate synchronously, and the ring sleeve 58 then drives the rotating shaft 52 to rotate synchronously through the torsion spring 510, and the rotating shaft 52 begins to drive the convex dial wheel 56 and the mounting cylinder 53 to reverse synchronously.

[0039] During the reversal of the convex dial wheel 56, its protrusion gradually moves away from the date frame 57, and then the two positioning clamps 51 are respectively moved away from each other under the reset push of the limit spring, and the positioning clamp 51 moves away from the cylindrical workpiece. During the rotation of the mounting tube 53 driven by the rotating shaft 52, the inclination angle of the mounting tube 53 will gradually decrease until the mounting tube 53 rotates to a horizontal state. Subsequently, the electric slide 11 is controlled to operate again to drive the C-shaped frame 3 to move a distance to the left. During the C-shaped frame 3 moves to the left again, it drives the synchronous cooling axial drilling mechanism 4 to operate, and axial drilling is performed on the cylindrical workpiece, so that the hole drilled axially at this time is connected with the inclined hole drilled radially before. Then, the self-clamping positioning radial drilling mechanism 5 is controlled to operate again, and the above-mentioned electric telescopic rod 592 pushes the rectangular frame 591 to start moving left, and the cylindrical workpiece moved to the next position is inclined radially drilled; the angle adjustment and positioning operations during inclined radial drilling can be combined and performed synchronously, which simplifies the drilling steps and facilitates continuous radial drilling of cylindrical workpieces.

[0040] See also Figure 5 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the synchronous cooling shaft drilling mechanism 4 includes a shaft plate 41 fixedly connected between the upper and lower opposite sides of the C-shaped frame 3, a drill rod 42 rotatably connected to the shaft plate 41, and a drive motor 43 fixedly connected to the right cavity wall of the C-shaped frame 3, the output shaft of the drive motor 43 is fixedly connected to the right end of the drill rod 42, an annular liquid storage tank 44 is provided on the outside of the drill rod 42, and a plurality of strip-shaped diversion grooves 45 connected to the annular liquid storage tank 44 are equidistantly provided on the left part of the outer wall of the drill rod 42. A liquid supply component 46 for inputting coolant into the annular liquid storage tank 44 is provided on the drill rod 42, and the liquid supply component 46 includes a plurality of L-shaped grooves 461 equidistantly provided in the circumferential direction in the drill rod 42 and a molded cylinder 462 fixedly connected to the outside of the drill rod 42 and connected to the right end of the L-shaped groove 461. The lower groove wall of the C-shaped frame 3 is fixedly connected to an annular cover 463 rotatably connected to the outside of the molded cylinder 462 through a connecting rod, and an input pipe 464 is connected to the outside of the annular cover 463.

[0041] When the C-shaped frame 3 moves to the left and drives the synchronous cooling axial drilling mechanism 4 to contact the cylindrical workpiece, the synchronous cooling axial drilling mechanism 4 is controlled to operate: the drill rod 42 is driven to rotate by the driving motor 43, and the drill rod 42 drills the cylindrical workpiece that contacts its left end from the axial direction as the C-shaped frame 3 moves to the left. When the drill rod 42 drives the annular liquid storage tank 44 to fully extend into the interior of the cylindrical workpiece, the annular liquid storage tank 44 and the inner cavity drilled by the cylindrical workpiece form a closed cavity together, and then the coolant is pumped into the input pipe 464, and the coolant then flows into the annular cover 463 and the I-type cylinder 462, and then the pumped coolant enters the L-shaped groove 461, and then the coolant is pumped into the annular liquid storage tank 44, and then divided into multiple tributaries and flows into the strip diversion groove 45, so that the coolant can repeatedly contact the inner cavity of the cylindrical workpiece for cooling treatment.

[0042] As the drilling depth of the drill rod 42 continues to increase, the position of the annular liquid storage tank 44 moves synchronously, and the annular liquid storage tank 44 drives the coolant to move synchronously, so that the cylindrical workpiece can always be cooled and cooled. When the drill rod 42 moves to the left and drills to the previously drilled inclined radial drilling position, the annular liquid storage tank 44 and the inclined radial hole will be connected together, and then the coolant after absorbing the heat generated during drilling will flow out from the inclined radial drilling hole and flush the drill chips in the drilling hole. The chips accumulated in the drilling hole during the drilling process are automatically cleaned.

[0043] After the coolant flows out of the inclined radial borehole for a period of time, the pumping of the coolant into the input pipe 464 is stopped. At this time, the drill rod 42 also stops rotating, and the self-clamping positioning radial drilling mechanism 5 operates to perform radial drilling processing on the next position. When the C-shaped frame 3 moves to the left again, the drill rod 42 can be controlled to rotate again to perform axial drilling of the cylindrical workpiece to the next depth. Then, the coolant can be pumped into the input pipe 464 again, and the above operation is repeated, so that the coolant flows into the annular liquid storage tank 44 to cool the real-time drilling location.

[0044] By utilizing the self-clamping positioning radial drilling mechanism 5 and the synchronous cooling axial drilling mechanism 4 to operate in combination with each other alternately, inclined radial drilling and axial drilling are performed on the cylindrical workpiece in turn. At the same time, it can also provide support for the right part of the cylindrical workpiece, thereby ensuring the overall stability of the cylindrical workpiece during drilling, avoiding the occurrence of offset, and improving the drilling accuracy.

[0045] See also Figure 1-Figure 10When working, firstly, the left end of the cylindrical workpiece is inserted into the clamping part 2, and the clamping part 2 is used to clamp and limit the left part of the cylindrical workpiece, and then the electric slide 11 is controlled to move to the left for a distance, and the electric slide 11 drives the C-shaped frame 3 to move to the left synchronously, and the C-shaped frame 3 then drives the self-clamping positioning radial drilling mechanism 5 to move to the position sleeved on the outside of the cylindrical workpiece, and then the self-clamping positioning radial drilling mechanism 5 is controlled to run to perform the first group of inclined radial drilling processing on the cylindrical workpiece. After the first group of inclined radial drilling processing is completed, the C-shaped frame 3 is driven to move to the left again by the electric slide 11 At the same time, the synchronous cooling axial drilling mechanism 4 is controlled to operate to perform axial drilling and cooling treatment on the cylindrical workpiece, so that the axially drilled hole is connected with the first group of inclined radial drilling holes, and then the electric slide 11 is controlled to stop temporarily, and then the self-clamping positioning radial drilling mechanism 5 can be controlled to operate again to perform a second group of inclined radial drilling processing on the cylindrical workpiece, and then the above steps can be repeated, and the C-shaped frame 3 is driven to move left again by the electric slide 11, and the C-shaped frame 3 drives the synchronous cooling axial drilling mechanism 4 to operate again, and the cylindrical workpiece is axially drilled to a deeper depth.
